OCLC Number/Unique Identifier: 9124851637

Naturally, microorganisms decompose the organic material existing in nature, both in the presence or absence of oxygen. The majority of materials such as poisonous chemical compounds, heavy metals, would prevent the treatment process from taking place, lead to the entry of these contaminants into the environment results in the emergence of numerous diseases. In the present study, using the TOXChem4.1 simulation model, attempts were made to simulate a wastewater treatment plant and then assess the dispersions of contaminants including 1,2-Dimethylnaphthalene, 1,3-Dinitropyrene, 1,6-Dimethylnaphthalene, 1,6-Dinitropyrene, and 17a-ethinylestradiol (EE2) in concentrations of a common scenario. The results of computer simulations showed that the EE2 contaminant is of the highest percentage of decomposition among others, due to its wider chemical structure. Consequently, it is clear that such contaminant is of the highest mass in the sludge exiting the treatment plant. In addition, the results of the simulations demonstrated that the highest volumes of gaseous pollutants take place in the modulation and initial sedimentation units.

Comparative Study of Cerebral Volumetric Variations in Patients with Schizophrenia with their Unaffected First-degree Relatives, using Magnetic Resonance Imaging Technique, a Case-control Study

Published on: 3rd January, 2024

Background and purpose: Schizophrenia (SZH) is a chronic mental disorder affecting the individuals` thoughts, perceptions, emotions, and behaviors. People with SZH may experience a wide range of positive, negative, and cognitive symptoms. Since there are no laboratory assays for definite SZH diagnosis, the authors aimed to identify the cerebral volumetric variations in SZH patients with the most prevalent positive symptoms as a diagnostic tool. This study selected 15 SZH patients displaying the most prevalent positive symptoms based on the Diagnostic and Statistical Manual of Mental Disorders (DSM-5) criteria. Assessment tools included the Mini-Mental State Examination (MMSE) for cognitive impairment, the Positive and Negative Syndrome Scale (PANSS) for symptom evaluation, and the Wechsler Intelligence Scale (WIS) for intelligence assessment. Additionally, 15 Healthy Controls (HC) without cerebral pathologies were recruited. T1w MRI images underwent analysis using Freesurfer software. Data analysis employed Mann-Whitney U and χ² tests, considering p < 0.05 as significant.Results: SZH and HC groups showed no significant differences in age and gender. However, significant (p < 0.05) alterations in Gray Matter (GM) volume were observed in SZH patients compared to HC. In the right hemisphere, several regions exhibited volume reduction, including the Fusiform sulcus, Rostral middle frontal gyrus, isthmus cingulate, Frontal pole, Middle temporal gyrus, Lateral occipital gyrus, and Inferior Parietal gyrus. Notably, the Precentral sulcus and Postcentral gyrus demonstrated volume acceleration. Similarly, in the left hemisphere, various regions showed volume reduction while the Paracentral gyrus indicated volume acceleration, all significant (p < 0.05).Conclusion: SZH patients display significant volumetric brain changes, indicating potential for future diagnostic procedures in SZH.

Noninvasive Cuffless Blood Pressure Monitoring. How Mechanism-Driven and Data-Driven Models Can Help in Clinical Practice

Published on: 12th July, 2023

Continuous noninvasive cuffless blood pressure (BP) monitoring is essential for early detection and treatment of hypertension. In this paper, we provide an overview of the recent advancements in cuffless BP sensors. These include contact wearable sensors such as electrocardiography (ECG), photoplethysmography (PPG), contact non-wearable sensors such as ballistocardiography (BCG), and contactless sensors such as video plethysmography (VPG). These sensors employ different measuring mechanisms such as pulse arrival time (PAT), pulse transit time (PTT), and pulse wave analysis (PWA) to estimate BP. However, challenges exist in the effective use and interpretation of signal features to obtain clinically reliable BP measurements. The correlations between signal features and BP are obtained by mechanism-driven models which use physiological principles to identify mathematical correlations, and data-driven models which use machine learning algorithms to analyze observational data to identify multidimensional correlations. On the one hand, applying mechanism-driven models to non-linear scenarios and incomplete or noisy data is challenging On the other hand, data-driven models require a large amount of data in order to prevent physically inconsistent predictions, resulting in poor generalization. From this perspective, this paper proposes to combine the strengths of mechanism-driven and data-driven approaches to obtain a more comprehensive approach, the physiology-informed machine-learning approach, with the goal of enhancing the accuracy, interpretability, and scalability of continuous cuffless BP monitoring. This holds promise for personalized clinical applications and the advancement of hypertension management.

Mapping the Psychosocial: Introducing a Standardised System to Improve Psychosocial Understanding within Mental Health

Published on: 9th February, 2024

Objective: Psychosocial approaches are increasingly being advocated as an efficacious means of addressing mental health problems. However, with a multitude of complex and varying interpretations present with the use of the term ‘psychosocial’ / ‘psycho-social’ in contemporary discussions of mental health, its application can be vague and even contradictory. This presents problems for research to inform practice and practice to inform research, ultimately inhibiting the help given to those suffering. Method: Literary review, reflecting an extended period of 10 years, explores and analyses the use of the terms ‘psychosocial’ and ‘psycho-social’ within a mental health context. Results: This article identifies that applications and use of the term psychosocial vary significantly, with two models being primarily evident in mental health applications: a multidisciplinary and interdisciplinary model. Conclusion: A standardised system is established for mental health theorists and practitioners to identify and categorise these different applications. This outcome is intended to lead to a better understanding of different psychosocial applications, provide better communication between existing psychosocial applications, and improve clarity for future instruction.

Calcium Scoring on CT Coronary Angiography in Hypertensive Patients as a Criterion for the Prediction of Coronary Artery Disease

Published on: 19th February, 2024

Introduction: Hypertension is the strongest independent predictor of Coronary Artery Disease (CAD) identified by Computed tomography of coronary arteries (CTCA). In this study, CTCA-assessed Coronary Calcium Scoring (CCS) was studied in hypertensive subjects referred for CTCA.Methods: After excluding TAVI and graft assessment patients, the individual electronic health records of 410 consecutive patients who underwent CTCA between July and November 2020, were reviewed with a mean age of 58.7 years. Risk factors were recorded including smoking (38%), hyperlipidaemia (33%), positive family history (22%), systemic hypertension (48%), diabetes mellitus (30%), and male gender (46%). Referral criteria, ethnicity, cardiac, and past medical history were recorded. Patients were stratified into four groups according to CAD severity: absent, mild, moderate, and severe disease, as seen on CTCA. The mean CCS for each CAD category was compared between hypertensive and non-hypertensive patients. Mean CCS were further compared according to the number of coronary arteries affected and the severity of CAD in each artery. Results: Out of all CTCA reports, 200 (48.8%) CCS were interpreted in the very low-risk category, 80 (19.5%) low risk, 58 (14.1%) moderate risk, 23 (5.6%) moderately high risk and 49 (12.0%) high risk. A significant difference in mean CCS and CAD severity was observed between mild, moderate, and severe CAD (p = 0.015 and p < 0.001). Comparison of CCS between hypertensives and non-hypertensives, across the four CAD severity categories, revealed a significant difference in mean CCS in the severe CAD category (p = 0.03). There was no significant difference in the CCS between hypertensives with chest pain and hypertensives without chest pain. A higher number of affected coronary arteries was associated with a higher mean CCS and a significant difference in CCS was observed between hypertensive and non-hypertensive subjects for the number of arteries affected. Similar results were observed when comparing mean CCS in moderate-severely affected coronary arteries.Conclusion: Hypertensive patients with a high CCS were associated with a higher incidence of severe CAD independent of the presence of chest pain. These results suggest that the incorporation of CCS in the investigation of CAD on CT angiography may pose a powerful adjunct in proposing an alternative paradigm for the assessment of patients with hypertension, in the progress of coronary artery disease.

Quality of Life (QoL) among Pakistani Women with Breast Cancer Undergoing Chemotherapy

Published on: 17th August, 2023

Background: Breast Cancer is the most common cancer in women and the quality of life of women with breast cancer is a significant healthcare issue specifically in developing and underdeveloped countries.Globally quality of Life (QoL) has become an important indicator to measure the outcomes of medical and nursing interventions. The QoL studies have an imperative role in healthcare especially in chronic disease as the latest diagnostic and treatment modalities have increased the survival rates and duration of cancer patients. Similarly, breast cancer itself and its treatment with Chemotherapy, in particular, has many complications and negative impacts on the QoL of cancer women. Aim: The aim of this study was to assess the QoL of Pakistani women with Breast Cancer patients undergoing chemotherapy and the relationship of QoL with socio-demographic variables.Methodology: A descriptive cross-sectional correlational study was conducted on 110 female breast cancer patients undergoing chemotherapy. FACIT-B questionnaire was used to assess the quality of life of these patients. Statistical analysis was done by using SPSS version 20 using the Pearson correlation coefficient, Chi-square test, and Spearman’s rho correlation coefficient. Results: The mean age of participants was (mean ± SD) 42.98 ± 8.98. A significant negative correlation was observed with age and QoL, r = -0.218, p - value 0.022. No significant association was observed between QoL and marital status; education status; and socioeconomic status.Conclusion: The majority of breast cancer women 59(53.6%) had moderate QoL and Chemotherapy also showed moderate impacts on different domains: physical, functional emotional, social, and sexual well-being of the women.

A Wolff-Parkinson-White (WPW) Electrocardiographic Pattern in Asymptomatic Patient – State-of-the-Art-Review

Published on: 7th June, 2022

A comprehensive approach to asymptomatic adults with Wolff-Parkinson-White (WPW) pattern discovered incidentally on routine electrocardiography (ECG) is debatable. The objective of this review article is to update the most recent evidence on the management of young patients with asymptomatic WPW patterns. A substantial proportion of adults with WPW patterns on ECG may remain asymptomatic but the lifetime risk for fatal arrhythmias still exists. The inherent properties of the accessory pathway determine the risk of sudden cardiac death. A low-risk pathway is considered when the pre-excitation is intermittent on ambulatory monitoring or when it disappears completely or abruptly during exercise testing. On the other hand, a high-risk pathway in EP study is suggested by the presence of the shortest pre-excited RR interval (SPERRI) during atrial fibrillation of ≤ 250 ms or accessory pathway effective refractory period (APERP) ≤ 240 ms. The cardiac evaluation may thus be considered in asymptomatic patients with WPW to determine the individual risk for future symptomatic arrhythmia. A shared-decision making must be performed before offering catheter ablation whose procedural success rate is high.

Cystic fibrosis and congenital adrenal hyperplasia: A rare occurrence with diagnostic dilemmas, similarities and contradictions

Published on: 20th October, 2020

OCLC Number/Unique Identifier: 8686101406

Cystic fibrosis (CF) is a hereditary syndrome composed of exocrine gland dysfunction involving multiple systems which if untreated may result in chronic respiratory infections, pancreatic enzyme deficiency and failure to thrive. The association between CF and other inherited diseases or congenital anomalies is rare. We describe a rare case of CF with concomitant congenital adrenal hyperplasia (CAH). 21- Hydroxylase deficiency accounts for most CAH cases. Varity in clinical phenotypes depends on the amount of enzymatic activity which in turn depends on different combination of gene mutations. The genes of CAH and CF are located in different locations. The chance of these diseases coexisting in our patient would be a rare combination. However, such a case will be more frequent in our population than others because of consanguineous marriage and common ancestors. There are diagnostic difficulties, similarities and contradictions between two diseases and they are pointed out.
